GATE-HINGE.

SPECIFICATION forming part of Letters Patent No. 234,382, dated November 16, 1880.

Application filed March 29, 1880. (Model) T 0 all whom it may concern Be it known that I, JOHN L. ANDERSON, a citizen of the United States, residing at Muncie, in the county of Delaware and State of Indiana, have invented a new and useful Improvement in Gate-Hinges; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon. which form a part of this specification.

The object of my invention is to produce a hinge that can be readily applied to an ordinary form of gate or door, such as farm-gates, barn and carriage-house doors,crib-doors, &c. 5 and it consists in details of construction hereinafter more fully set forth in the specification, and pointed out in the claims and accompanying drawings, in which- Figure l is a side elevation of my device; Fig. .6, a plan view; Fig. 3, a perspective view, showing its application to a gate; Fig. 4, a plan view of same, showing the gate turned transversely after being opened. Figs 5 and 6 show the application of the hinge to a door. Fig. 7 is a section of the hinge on the line at m, Fig. 2.

Heretofore in this class of hinges the upper or supporting bar of the gates has been supported on a wheel journaled in open standards between which the bar is placed, or in two such wheels journaled in two open standards, having a friction-wheel on the top of each standard branch. In such hinges the journals of the wheels are liable to break or wear unevenly, and render the hinge inoperative for the purpose. I propose to remedy these defects and to simplify the construction of gatehinges by placing or resting the bar I) of a gate on two double convex washers, E, encircling and moving around two stationary gudgeons, F, cast on the movable base L. The bar b nearly fills the space between the gudgeons which rest upon or are cast with a movable base, L, which turns freely around a pintle, H, on the screw-hook M.

WVhen the gate is moved back and forth the washers E turn on the gudgeons F and have a rolling motion around them, and at the same time carry back and forth the upper bar, I), and in consequence the gate or door. When the gate or door has been pushed back in this way about half its length or to a point where it is balanced, it is swung around parallel to the passage-way by turning the base L around pintle H, as shown in Fig. 4.

In the case of doors for barns, &c., the door may be pushed back its entire length without swinging transversely.

The hook M is inserted in the corner of the gate or door-post, and stands out at the same angle with the post as if it were inserted from corner to corner of the post.

The pintle H is formed in one piece with the hook, and extending upward at right angles therewith enters an opening in the movable base L, supported on a shoulder of the hook.

The hook may be readily inserted in a gate or door postby screwing or driving it into the post. The gate may be readily attached to or detached from the hinge by simply lifting it on or off the upper bar. It will be necessary to use a strip or auxiliary bar on a door, so that said auxiliary bar can rest on the washers E, or the top of the door may be slotted and the hook and base inserted sidewise, and then the upper part of the door allowed to rest on the washers.

The several parts of the hinge, being detachable and simple in construction, are easily replaced or repaired.

The hinge can be made of any suitable materialsuch as iron or brass-and of any convenient size, depending on the size of the gate or door to be hung upon it.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination of a screw-hook, M, having a pintle, H, inserted in a movable base, L, provided with two stationary gudgeons, F, with the two double convex rollers E resting on the base L and movable around the stationary gudgeons, substantially as described.

2. In a hinge, the combination of a movable base, L, having two vertical gudgeons, with the detachable rollers E resting on the baseL and supporting the upper bar of a gate, substantially as described.

In'gtestimony whereof I at'fix my signature in presence of two witnesses.

JOHN L. ANDERSON.
